I needed to render some ocean, but in 3Delight. So I 'ported' the VEX shadeop to RMan. The code is only tested with 3Delight on win32 but I'm confident it should work on Linux/OSX and with PRMan as well. This is a "new school" RSL plugin shadeop, so it processes entire grids instead of single shading samples. The shadeop works in multi-threaded mode in 3Delight and I'm confident it should as well in PRMan. Let me know if anyone wants the copy or if you want to make this part of the HOT package
